Answer 2

Answer:

(i) (a)

(ii) (d)

(iii) (b)

(iv) (a)

(v) (c)

Step-by-step explanation:

(i) The answer is (a) because the graph cuts the X-axis at these points only.

PRO-TIP: Whenever you're asked to name points where a graph cuts the X-axis, remember that the ordinates of those points will always be zero. The only option which satisfies this condition is (a).

(ii) No. of zeroes = No. of points the graph cuts the X-axis (ie number of values of x such that the polynomial y is zero). Thus, the correct answer is (d).

(iii) The graph cuts x-axis at -5, -2 & 2. Thus, its roots are these three numbers. (b) is the correct option here.

(iv) The only polynomial which gives zero when we put x as -5, -2, 2 is (a). Thus, (a) is correct here.

(v) You can see from the graph that when x = -5, y = 0. This means that when we put x = -5 in the polynomial, we'll get y (which is the polynomial function here) = 0.
